Every tool has a clearly distinct purpose with no ambiguity, as each is prefixed by its domain (e.g., calendar_, contacts_, finder_) and specifies a unique action (e.g., create_event, get_calendars, get_selection). The domains are well-separated, preventing misselection.

Tool names follow a highly consistent verb_noun pattern with domain prefixes (e.g., calendar_create_event, contacts_search_people). All use snake_case uniformly, and the naming structure is predictable across all 24 tools, making them easily readable and organized.

With 24 tools, the count is slightly high but reasonable for the broad scope of macOS automation covering multiple domains like calendar, contacts, mail, and notes. Each tool earns its place by addressing specific tasks, though it borders on heavy for a single server.

The tool surface provides strong CRUD/lifecycle coverage across domains, with create, get, and search operations for most resources. Minor gaps exist, such as no update/delete for calendar events or notes, but agents can work around these for core workflows.
